there is this:
4 x 100 Front Disc Brake Conversion for EG/EK | JDM Honda Parts, JDM Honda Engines / JDM Nissan Motor Swaps, Used JDM Parts - Password JDM
but it doesnt include lca's and the shipping is more than the parts.

i have always heard good things about these guys:
Import Auto Salvage

check with Driven Concepts, they might have some parts laying around

search the h/a for sale forums, there are usually a few people selling full brake upgrades for pretty cheap
